ABC Logic Self Calibration T8100 and T8300 single channel sensors employ the patented ABC (Automatic Background Calibration) Logic self-calibration system. ABC Logic virtually eliminates the need for manual calibration in applications where the indoor CO
2 level drops to outside levels during
unoccupied periods (e.g. during evening hours). ABC Logic is a special software routine in the sensor that remembers the background readings for 14 consecutive evenings. calculates if there is a sensor drift. and then corrects for it.
With ABC Logic enabled, the sensor will typically reach its operational accuracy after 25 hours of continuous operation at a condition that is exposed to ambient reference levels. Sensors will maintain accuracy specifications with ABC Logic enabled, given that it is at least three times in 14 days exposed to the reference value and this reference value is the lowest concentration to which the sensor is exposed.
Note: Applies when used in typical indoor ambient air. Consult Telaire if other gases or corrosive agents are part of the application environment.
CO2
Calibration Guarantee Telaire is serious about minimizing maintenance, so each single-channel sensor (T8100/T8300) comes with a lifetime calibration guarantee. And each dual channel sensor has a two-year calibration guarantee (T8200).
Calibration Interval For T8100 and T8300 series, no calibration is required due to ABC Logic. For T8200 series, annual calibration is recommend for the best accuracy. However. most applications using T8200 series could extend the calibration interval. For the humidity sensor, no calibration is required. Replacement humidity sensors are available.
If a Telaire 8000 series single channel sensor drifts out of calibration range, it can be sent back to Telaire for a free factory calibration. Further information on the guarantee is available on our website.
T8200 - Dual Channel The T8200 dual channel sensor can be described as a CO
2 channel that measures gas concentration and
a reference channel that measures the sensor signal intensity. The dual channel sensor performs periodic self-calibrations using the reference channel. The selfcalibrations are approximately every 24 hours. During the self-calibration the sensor ppm reading is frozen. it will not react to changing CO
2• The calibration time is
adjustable but nominally two minutes.
Telaire recommends periodic gas calibration depending on the application accuracy requirements. While the reference channel corrects for changes over time. a field calibration using nitrogen gas or alternatively ambient calibration will immediately restore the highest level of accuracy. Refer to the calibration manual for details.

8300 Pitot Tube Configuration
The pitot tube kit is used for duct measurement of CO2
•
The pitot tube is installed in the duct and the sensor is mounted remotely, which allows for easy access.

Enhanced Field Serviceability
The Ventostat 8000 series features a field-replaceable Relative Humidity (RH) sensor tip module that allows the end user to replace the sensor on-site while maintaining ±2.5% RH accuracy. The user simply powers off the unit, installs the new sensor module and powers back the unit. This virtually eliminates the need for time consuming and costly factory calibration, while reducing downtime during service intervals to near zero. The sensor is protected from dust contamination by a specially designed filter as shown in the photo below.
